下面的代码给出

未捕获的错误：您必须将一个组件传递给 connect 返回的函数。而是收到未定义

列表.js

import React from 'react';
import { connect, bindActionCreators } from 'react-redux';
import PostList from '../components/PostList'; // Component I wish to wrap with actions and state
import postList from '../Actions/PostList' //Action Creator defined by me

const mapStateToProps = (state, ownProps) => {
    return state.postsList
}

const mapDispatchToProps = (dispatch) => {
    return bindActionCreators({"postsList":postList},dispatch)
}

export default connect(mapStateToProps, mapDispatchToProps)(PostList);

PostList.js

import React from 'react'

export const PostList = (props) => {
    return <div>List</div>
}

请帮我解决一下？
